  • Patent number: 5817634
    Abstract: This present invention provides a method and compounds for priming the incorporation of cellular glucose into an oligosaccharide in a cell comprising administering to the cell a priming amount of a membrane-permeating nontoxic glycoside having a suitable hydrophobic organic group joined by a linkage to a suitable hydrophilic saccharide, wherein the hydrophilic saccharide has a nonreducing terminal sugar residue selected from the group consisting of glucose or xylose, thereby priming the incorporation of cellular glucose onto the glycoside to form an oligosaccharide.
